The former Democratic presidential nominee responded with a stinging tweet to the release Thursday of the Justice Department inspector general’s report on the handling of the FBI’s investigation into Clinton’s use of a private email server and email address when she served as secretary of state.

The inspector general’s report faulted former FBI Director James Comey for his decision to publicly launch an investigation into Clinton’s email use, including his decision to hold a July 5 press conference without informing his DOJ superiors, that many believe had an impact on the 2016 presidential campaign.

“It was extraordinary and insubordinate for Comey to do so,” Inspector General Michael Horowitz wrote in his report, “and we found none of his reasons to be a persuasive basis for deviating from well-established department policies in a way intentionally designed to avoid supervision by department leadership.”

Specifically, Horowitz cited Comey’s decision to send a letter to Congress on Oct. 28, 2016, announcing that he was reopening the investigation into Clinton’s use of a private email server without first consulting officials at the Department of Justice.

Clinton has remained steadfast in her insistence that Comey’s letter helped tip the election in Donald Trump’s favor.

“I was on the way to winning until a combination of Jim Comey’s letter, on October 28, and Russian WikiLeaks raised doubts in the mind of people who were inclined to vote for me but got scared off,” Clinton said at a 2017 event titled Women for Women International.

Perhaps even more difficult to swallow for Clinton and her supporters, however, is the IG’s finding that Comey himself used a private email account while at the FBI.
